a rectangle has a length of 4 inches and a width of 2 inches. if the length and width of the rectangle are each reduced by 50% by what percent will be reduced?

Question

how is the answer 75%

Answer 1

Area at beginning = LW

 

When reduced, length becomes ½L, width becomes½W.

 

What's new area? (½L)(½W) =  ¼LW so this is 25% of the original area.

therefore 75% reduction.
